GWYNNE DYER has worked as a freelance journalist, columnist, broadcaster and lecturer on international affairs for more than 20 years, but he was originally trained as an historian. Born in Newfoundland, he received degrees from Canadian, American and British universities, finishing with a Ph.D. in Military and Middle Eastern History from the University of London. He served in three navies and held academic appointments at the Royal Military Academy Sandhurst and Oxford University before launching his twice-weekly column on international affairs, which is published by over 175 papers in some 45 countries.

His first television series, the 7-part documentary 'War', was aired in 45 countries in the mid-80s. One episode, 'The Profession of Arms', was nominated for an Academy Award. His more recent television work includes the 1994 series 'The Human Race', and 'Protection Force', a three-part series on peacekeepers in Bosnia, both of which won Gemini awards. His award-winning radio documentaries include 'The Gorbachev Revolution', a seven-part series based on Dyer's experiences in Eastern Europe and the former Soviet Union in 1987-90, and 'Millenium', a six-hour series on the emerging global culture.

Dyer's major study "War", first published in the 1980s, was completely revised and re-published in 2004. During this decade he has also written a trio of more contemporary books dealing with the politics and strategy of the post-9/11 world: 'Ignorant Armies' (2003), 'Future: Tense' (2004), and 'The Mess They Made' (2006). The latter was also published as 'After Iraq' in the US and the UK and as 'Nach Iraq und Afghanistan' in Germany.

His most recent projects are a book and a radio series called 'Climate Wars', dealing with the geopolitics of climate change. They have already been published and aired in some places, and will appear in most other major markets in the course of 2009.

Global warming is moving much more quickly than scientists thought it would. Even if the biggest current and prospective emitters - the United States, China and India - were to slam on the brakes today, the earth would continue to heat up for decades. At best, we may be able to slow things down and deal with the consequences, without social and political breakdown. Gwynne Dyer examines several radical short-and medium-term measures now being considered - all of them controversial.
